IPC: G01B11/00
Filed: 1989-09-19
Abstract: PURPOSE:To correctly detect the positional information of a thin-plate-like object by a simple mechanism by calculating the position of the object on the basis of the phase information obtained by a plurality of photodetectors. CONSTITUTION:An object 4 to be detected moves in such a direction as to traverse a measuring light path in a thicknesswise direction thereof. There is a phase difference in currents output between a photodetector 8 and a photodetector 9 when the object 4 moves from a position A to a position B from when the object 4 moves from the position B to the position A. The positions of an upper surface and a lower surface of the object 4 are detected on the basis of the output currents and the phase difference by a detecting circuit. Accordingly, by obtaining the phase information of the two photodetectors in this construction, it becomes possible to suppress influences of the diffraction, mechanical vibrations etc. and to realize highly accurate detection of a position.
